The important elements of a drought phenomenon are the longest duration and the largest severity for a desired return period. These elements form a basis for designing water storage systems to cope with droughts. At times, a third element, drought intensity, is also used and is defined as the ratio of severity to duration. The commonly available statistics(More)
Estimation of direct runoff volume and peak runoff rates for small rural catchments in Kenya, East Africa, poses a problem in view of the limited gauged data available. The problem can be circumvented by adopting a modelling approach. This, however, does require some base data for model calibration and validation. A highly reliable data base for two small(More)
In this paper, we propose an integrated reliability/availability modeling and analysis environment suitable for heterogeneous hierarchical system analysis. A key component of this environment is a high level system specification and input language which acts as a common interface to several off-the-shelf reliability modeling and analysis tools (Koren JM,(More)
