Gladys Chelangat
Ms Gladys is a Research Scientist at the Kenya Agricultural and Livestock Research Organization (KALRO) under the Food Crop Research Institute (FCRI) based at Kabete research centre in Nairobi.
She obtained her MSc. in Agricultural Engineering from the Szent Istvan University, Hungary (2014) where she specialized in Water Resources Management (Catchment Hydrology). She also has a BSc. in Agricultural Engineering from Egerton University, Kenya. She started working at KALRO in 2015 after the completion of her MSc Degree. She has also been trained in many professional courses both nationally and regionally which has earned her as a trainer on irrigation, drainage and water management for international fellows at KALRO.
Her main expertise as Agricultural Engineer is in areas of Soil and Water Management, Irrigation Engineering. She is experienced in the application of hydrological models in solving water resources challenges especially in river basin management, modelling of sediment transport, assessment of water quality issues, as well as climate and land use changes studies.
Ms Gladys is involved in a number of research activities at KALRO in the areas of Food Security, Irrigation and drainage, soil and water management, including KCSAP (Kenya Climate Smart Agriculture Project). She is a member of Engineers Registration Board and the Eastern Africa Association of Radiation Protection.
Ms Gladys desires to continuously contribute her professional expertise towards realizing the Kenyan Vision 2030 and Sustainable Development goals.

This study explored the potential of Hydrologic Engineering Centre-Hydrologic Modelling System (HEC-HMS 3.5) in conjunction HEC-GeoHMS extension in ArcMap 9.3 or ArcView as a tool for water management in upper catchment, Mara River Basin. GIS layers that were needed as input data were prepared using ArcMap 9.3. HEC-HMS is a semi-distributed model which focuses on rainfall-runoff processes and simulation were applied on a daily scale. The model was calibrated and validated using the 2005 and 2006 data set respectively. The evaluation of the model was tested statistically employing the correlation coefficient (R2), Relative Error (RE), and Nash-Sutcliffe Efficiency Index (EI). The R2 for Nyangores and Amala during calibration and (validation) were 0.53 (0.41) and 0.21 (0.24) respectively where else the EI during calibration and (validation) were 0.93 (0.91) and 17.10 (0.46) for Nyangores and Amala respectively. The model shows great potential in simulating the wet season runoff. The application of HEC-HMS model is considered to be satisfactory for Nyangores sub-catchment but further research is needs to be undertaken to access the results of Amala sub-catchment.
