Query: A Stochastic Hydrological Model for Regulation of Lake Malawi Shire
  River system   Located in Liwonde in the Southern Region of Malawi, Kamuzu Barrage is the
only facility for regulation of water flow down Shire River, which has a major
influence on water levels in Lake Malawi. In this article a hydrological model
for optimized operation of the Kamuzu Barrage called the Kamuzu Barrage
Operation Model (KABOM) is presented. This model is a tool for water resource
management at the Kamuzu Barrage based on stochastic hydrology. The stochastic
model uses water level readings at Lake Malawi and at the Shire River near
Liwonde stretching from January 1900 to date. By using historical rating curves
at Liwonde, and developing an updated post-2003 flood rating curve, the model
can calculate flow at Liwonde for the entire period. The model simulates
available water budgets for a range of probabilities based on the Lake Level
and flow record over the past 115 years, plus available data on local inflows
to the Shire River from its tributaries. The results provide a basis for
choosing a release strategy in Kamuzu Barrage, which is used in optimizing the
release at the barrage on daily basis. Resulting quantiles display a strong
seasonal variation, highest Freewater forecasts within February and March in
the rainy season, and the lowest months of June and July in dry season. The
results for simulation are controlled against actual Freewater values in the
period of December 2016 to October 2017, which demonstrates a satisfactory
validation
