Abstract
Joint activities for global water partnerships in regional development programs are usually facilitated by implementing transboundary water projects. Most projects are however hampered by the absence of a clear economic base for making investment decisions. In this paper, we propose a zero-one integer programming model to determine the optimal decisions for selection of project portfolios on transboundary waters; where project selection is based on several time periods in the future.The objective is to determine whether to undertake a project or not; so that the net present value of investment returns is maximized to support needy communities. A numerical example is presented for illustration; demonstrating the optimal choice of investment projects under budget constraints. The zero-one integer programming model provides a feasible solution for choice of transboundary project investment decisions; given the competing nature of capital budgets prior project implementation. The proposed model can be efficient; where limited funds among competing projects serve as a basis for project selection criteria; a decision for facilitation enhancement towards water partnership for regional development.

Transboundary water projects are vital for cities and the towns around the world; supporting the livelihood of vast numbers of people
In UNECE [6], the report indicates lack of financial resources, inadequate funding and financial mechanisms can impede transboundary water cooperation and basin development even if all states are committed to it.In order to strengthen the capacity of transboundary water management, a project was undertaken to create a framework for cross fertilization and exchange of experience between river basins and countries on regulatory, institutional, methodological and other aspects of integrated transboundary waters

Summary
Transboundary water projects are vital for cities and the towns around the world; supporting the livelihood of vast numbers of people. In UNECE [6], the report indicates lack of financial resources, inadequate funding and financial mechanisms can impede transboundary water cooperation and basin development even if all states are committed to it.In order to strengthen the capacity of transboundary water management, a project was undertaken to create a framework for cross fertilization and exchange of experience between river basins and countries on regulatory, institutional, methodological and other aspects of integrated transboundary waters. The world bank’s technical report[16] for Nile basin initiative considers regional investment projects for the economic and social development of water resources, as well as for the improved management of water resource projects re selected, screened and national level project prioritization is done prior receiving funding approval It requires making optimal use of the capacity that is available; as well as necessary structure and mechanisms in place for accelerated and smoother implementation of projects. 4.2 Constraints The first constraint indicates that the total capital on all transboundary water project investments undertaken is less than or equal to the capital available
