I have had the opportunity to know Mesfin at personal and professional levels while at Arba Minch University. He is reliable, dedicated and always striving to greatness. I have always admired his passion and love for the profession of water resources.

Well, where can I start the story! Mesfin and I were very close and I knew a lot about Mesfin. We both studied from early elementary class until high school. As we were in the same class, we used to study together, play together, and do everything together. Even we hung-out together during our vacation times. Obviously, I cherished his friendship while studying with him all along with the 9th grade up to the final high school class. As a friend, we were inseparable. Upon completion of our high school studies, we separated because we went to different universities. He went on to continue studying engineering and I went on studying Pharmacy. My profession is a pharmacist. I worked as a pharmacist at the Adama Hospital Medical College in Nazareth city for several years, more than 20 years to be precise. Later on, I became a manager of my own pharmacy in Nazareth city, Ethiopia. I love my work and appreciate my profession. Therefore, as my experience suggests, I am in a better position to explain unambiguously Mesfin's upbringing, early education, and skills. As per my recollection in our early studies, Mesfin was a much disciplined, hard worker, well mannered, and exceptionally respectful to his seniors. I never saw him faltering while doing his studies. He was on top of everything, he managed well everything and later joined the university with ease. He enjoyed studying as much as life. I am a living testimony that Mesfin was very preserving, a person work in hard conditions impeccably, and a person committed to his scientific studies. Not only committed but he has also all the necessary competence to accomplish a great task, the capacity to overturn any situation into profits. He was an inspiration to all of us and I hope he still is to others, if you need to know more about Mesfin, please give me a call so that we can chat about his upbringings and competencies.---------------------

Mr. Mesfin Tewolde is one of my colleagues while we were both working for the Ministry of Agriculture, in Eritrea, at the Keren Branch office of the ministry. He used to construct dams and weir structures. I used to work in a similar territory and regularly visit his dam construction site. Given that, the region is very underdeveloped and even did not have the vital supplies, I witnessed him working in those harsh conditions impeccably. Quite a while later, I even saw personally after the finish of the construction of the dam that it has profited the residents tremendously. The locals utilize the dam hold for Irrigation and drinking purpose. Later we both got an opportunity to a post-graduation study at the University of KwaZulu-Natal; South Africa, where we become personal companions. We used to live in the same apartment and we were exceptionally too close. This is when; I get the opportunity to see a greater amount of his works and his capacities accomplishing assigned tasks. For the most part, we study in research facilities together and I have seen him doing his Master’s research project in hydrology. I noticed that he was persevering and committed to the research he was assigned to work on. Mr. Tewolde is well mannered, communicates easily with anyone, he is friendly and pleasant to work with. Moreover, he always gives helping hands to those who require his expertise. Therefore, I recommend Mr. Tewolde to any opportunities and I am certain that he will be a great asset to any organization that needs his expertise.

I believe I am a living witness of his work experiences and professional competencies, as we both worked and studied together for such a considerable time, both in Eritrea and in South Africa. During the years, we spent together working for the Ministry of Agriculture (MOA) in Eritrea. Although Mesfin used to work at the central office in Asmara, he frequently visits us in the southern region, where I used to work. I visited his dam construction sites several times and worked in collaboration with him on related projects as well. This helped me to know him better. Mesfin is highly motivated who tirelessly devotes all his time and energy to science and discovery. In Eritrea, while working for the MOA, Mesfin has contributed a lot to improving the lives of many farmers through the dam project endeavors. I met Mesfin later during wartime when we both called up for the Eritrean National Military Service duty under the Ministry of Defense orders. We both served together at the port city of Assab, Eritrea. During those days, Mesfin passionately contributed his expertise in the construction of a new large hospital building complex. The Hospital completed on time and offered tremendous regional service during the long years of the Eritrean & Ethiopian border war. Mesfin and I also spent considerable time together studying at the University of KwaZulu-Natal, South Africa. We used to discuss our master's projects and other scientific articles. That was when I saw him working on his hydrological project theses daily. Moreover, I have read his published hydrology journals as well. It was a highly referred journal. That is the result of his long years of practical experience and dedication to the subject. On a personal level, he is cordial and pleasant to work with. Mesfin is a much disciplined and well-mannered person. He is surely diligent to cooperate with and happy to share his expertise with anyone who needs his support. Therefore, I surely recommend Mesfin for any organization that needs his expertise and I am certain that he will add esteems to any institute that may require his skills.

Flood MappingL’ingénierie hydraulique et l’ingénierie hydrologique, bien que proches et souvent complémentaires, sont des domaines d’expertise distincts. Chacun exige des connaissances et des compétences spécialisées, et il est essentiel de comprendre les différences entre eux pour apprécier leurs contributions uniques à la gestion de l’eau et au développement des infrastructures.
J’ai rencontré des individus provenant de domaines tels que la dendrologie, les sciences de l’environnement et la géographie physique—des disciplines ayant leurs propres contributions précieuses—qui se qualifient de hydrologues ou d’ingénieurs hydrauliciens. Certains affirment même être compétents dans les deux domaines. Bien que ces disciplines soient respectées et contribuent à notre compréhension des systèmes naturels, les complexités de l’hydrologie et de l’hydraulique nécessitent une expertise plus ciblée qui dépasse ces domaines.
Lorsqu’une personne se dit à la fois hydrologue et ingénieur hydraulicien, cela suggère souvent une mécompréhension des principes fondamentaux qui définissent chaque domaine. Bien que ces deux disciplines soient liées, leur champ d’application et leurs objectifs diffèrent considérablement, et maîtriser les deux simultanément peut s’avérer un défi. Une compréhension approfondie de l’hydrologie et de l’hydraulique exige une formation spécialisée et de l’expérience dans chaque domaine, car leurs méthodes et leurs objectifs sont distincts.
Les deux domaines nécessitent une solide formation en génie civil. Les ingénieurs hydrologues se concentrent sur le comportement et le mouvement de l’eau dans les systèmes naturels, en étudiant les précipitations, les nappes phréatiques et la dynamique des bassins versants. Les ingénieurs hydrauliciens, quant à eux, se concentrent sur l’application pratique de la gestion de l’eau, en concevant des systèmes tels que des barrages, des pipelines et des structures de contrôle des inondations. Les principes du génie civil sont essentiels dans les deux domaines, ce qui rend difficile, voire impossible, d’exceller dans ces disciplines sans une solide formation dans ce domaine.
Bien qu’il soit vrai que l’hydrologie et l’hydraulique puissent se compléter, elles demeurent des domaines séparés, chacun nécessitant des compétences et des approches différentes. Pour réussir véritablement dans l’un de ces domaines, il faut développer une compréhension approfondie des principes fondamentaux et des méthodologies qui définissent ces professions.
Pour clarifier davantage la distinction :
Hydrologie de l’ingénierie
Définition : L’hydrologie de l’ingénierie se concentre sur la compréhension et la gestion des systèmes naturels d’eau, y compris leur mouvement, leur distribution et leur qualité. Les hydrologues analysent les précipitations, les débits fluviaux et les nappes phréatiques pour évaluer la disponibilité de l’eau, les risques d’inondation et l’impact environnemental.
Activités clés :
Analyse des précipitations et du ruissellement : Évaluer la disponibilité de l’eau et les risques d’inondation.
Évaluation des risques d’inondation : Étudier la fréquence des inondations et développer des stratégies d’atténuation.
Études des nappes phréatiques : Évaluer l’extraction durable de l’eau.
Gestion des bassins versants : Gérer la qualité de l’eau et la santé des écosystèmes.
Applications :
Gestion des eaux pluviales, Atténuation des inondations, Planification de l’approvisionnement en eau.
Hydraulique de l’ingénierie:
Définition : L’hydraulique de l’ingénierie traite du contrôle du flux d’eau dans les systèmes créés par l’homme, y compris la conception et la gestion d’infrastructures telles que les barrages, les pipelines (canalisations) et les infrastructures de contrôle des inondations.
Activités clés :
Analyse du flux de fluide : Comprendre comment l’eau se déplace dans les systèmes.
Conception hydraulique : Concevoir des barrages, des digues et des systèmes de drainage.
Systèmes de pression de l’eau : Gérer la pression dans les systèmes urbains et industriels.
Contrôle du flux : Concevoir des vannes, des déversoirs et d’autres structures régulant le flux de l’eau.
Applications :
Infrastructures de contrôle des inondations, Systèmes d’approvisionnement en eau et d’assainissement, Systèmes d’irrigation et de production d’hydroélectricité
Différences clés
Objectif : L’hydrologie se concentre sur le comportement naturel de l’eau, tandis que l’hydraulique concerne les systèmes d’eau artificiels.
Portée : Les hydrologues étudient de grands systèmes tels que les bassins versants, tandis que les ingénieurs hydrauliciens conçoivent des structures spécifiques pour le contrôle de l’eau.
Application : Les hydrologues évaluent les patterns de l’eau et gèrent les ressources en eau naturelles, tandis que les ingénieurs hydrauliciens conçoivent et optimisent les infrastructures pour une gestion efficace de l’eau.
En conclusion, bien que ces deux domaines soient liés et se complètent, ils nécessitent des compétences et des approches distinctes, soutenues par une solide formation en génie civil.

Champ has got a trophy today!

Sport for Health
Outdoor activities such as hiking and cycling make my days better.
Today (20201228) due to weather conditions, I interrupted my cycling activities at 21 Kms. However, I noticed that my hours are getting better after repeated training sessions.
This week’s challenge was cycling. The above-indicated images are morning cycling activities. The dates are from 20201210-20201221. These were only 10 days of challenge and the cycling activity will continue…… In the same month, there were hiking activities as well. Because of my achievements, I think I am a champion LOL! Now you can call me Champ.
Professor Roland Schulze, UKZN Hydrology Professor Emeritus and Senior Research Associate in the Centre for Water Resources Research (CWRR), received a Lifetime Achievement Award at the African Utility Week Industry Awards which recognises energy and water influencers in Africa.
Over 600 guests from 30 countries attended the glamorous black-tie event, many of them Africa’s most renowned power and water industry professionals. Schulze was selected winner of the Lifetime Achievement Award by a panel of 22 international judges.
‘This is a proud and emotional moment and a humbling experience,’ said Schulze, who also reflected on the individuals and institutions who influenced his outlook and success, including his parents whose dreams were cut short by the Great Depression, leading them having to curtail their schooling at the age of 14 to start work.
Schulze, who completed his undergraduate, Honours, Masters and PhD studies at the then-University of Natal, began his career as a high school teacher of Science and Mathematics, joining his alma mater in 1969 where he worked until formal retirement in 2007. He piloted South Africa’s first hydrology degree course in the early 1980s; the discipline grew under his leadership to form the CWRR, now training more than 150 undergraduate students and 30 postgraduate students from around the world annually.
Schulze was also visiting professor at the IHE Delft Institute for Water Education in The Netherlands and at the Swedish Meteorological and Hydrological Institute. He has been involved in more than 100 short courses on hydrological modelling and climate change in South Africa, Africa and Europe.
Schulze’s involvement in national and international level hydrological research spans more than 50 years. For the past 30 years, he has been pursuing applied climate change research. Landmark achievements include development of the Agricultural Catchments Research Unit (ACRU) agro-hydrological modelling system and the SCS-SA design hydrology simulation model.
He has over 600 varied publications to his name, from refereed journal papers to books and popular articles, with further publications forthcoming. He has spent six sabbaticals at institutions in the United Kingdom, Germany, the United States and The Netherlands. Schulze has supervised 67 Masters and 20 PhD students, with eight students currently under his supervision. His graduates have gone on to make a considerable impact in various sectors.
Schulze’s accolades include a Fellowship of the University of Natal, a Fellowship of the Royal Society of South Africa, Life Membership of the International Water Academy in Norway, a South African Institute of Agricultural Engineers (SAIAE) Fellowship, Membership of the Academy of Science of South Africa and numerous “Best Lecturer” awards. He is the recipient of Gold and Silver Medals from the SAIAE. read more
