A system dynamics simulation model for the assessment of water resources in Sri Lanka
conference contribution
posted on 2018-02-12, 15:09 authored by K.D.W. Nandalal, S.B. SemasingheAbility to accurately predict water availability in a country is vital in planning its water resources development activities.
Traditional approach used is based on a water balance and a demand projection. The projections are variant of current
trends and subject to considerable uncertainty. Besides, they do not capture dynamic character of climatic, socio-economic
and environmental change etc., and their impact on water use. Thus, the traditional approach is subject to a wide margin
of error. In contrast, a novel approach, “system dynamics” offers a new way of modeling future dynamics of complex
water systems increasing the ability to correctly assess and predict availability and use of water. This paper presents a
system dynamics based simulation model to predict water resources in Sri Lanka. Using the model water availability was
predicted and Sri Lanka will have sufficient water in the year 2025. However, in several districts water availability will
decrease rapidly while others will not get much affected.
