Water‐Balance Model of Two Conservancies in Guyana

Abstract

A hydrological water‐balance model used for the Nanni swamps in Surinam is adjusted and applied to a similar swamp in coastal Guyana. A water balance study was performed in Guyana on two water conservancies; the Boe rasirie water conservancy and the East Demerara water conservancy. For the Boerasirie water conservancy the model is calibrated on a daily basis using the Boerasirie Conservancy Board records of 1987. The model calculates water levels using rainfall, evapotranspiration, agricultural use, and spill over different weirs. Calculated and measured water levels are compared, and parameters in the model are adjusted to minimize the difference. The conclusion is that the adjusted model gives results for the situation in Guyana over a wide range of water levels.
