Research Abstract

A core site was established in a rural area under a savanna agro-ecologicalzone of West Africa, to implement field studies including installation of several water controlling structures. Focusing on stochastic differential equations, mathematical modelling methods were integrated to clarify scientific implication of the field studies. Numerical analysis models were constructed as well, so that practical optimal water resources development options became feasible. These achievements demonstrated stochastic optimization methods for design and management of storage systems, emphasizing on coexistence of rice cultivation and fishery.
