INSTITUTIONS & ECONOMICS
 SR TOOL IVa01 – WEAP MODEL INCLUDING
PARAMETER ESTIMATION (PEST)

applicable at multiple scales, from community to
catchment to basin. WEAP Model:
 Uses scenarios to evaluate different water allocation
possibilities
 Can be linked to groundwater model (MODFLOW)

livelihoods assessments based on water allocation

 SR TOOL IVa02 – FINANCIAL ACCOUNTING MODEL
 Tool is to convert the outputs of a water planning model
(like WEAP) into variables useful for decision-making by
planners and farmers. The tool is designed for the
following purposes:
 to estimate the initial and recurring farm-level costs of
water-related infrastructure,
 including capital investment and amortization,
 and operational expenses
 and to estimate the price and income consequences for
farmers of increased production (higher yields, increased
planted area) of particular crops

 SR TOOL IVa03 –WATER-LIMITED YIELD MODEL
 Tool estimating the effect on yields of climate and
weather (deviations from average rainfall patterns such
as drought; climate change) and to estimate the effect
on yields and water consumption of improved irrigation
practices.
 It models crop yields under water-limited conditions and
irrigation efficiency for different irrigation techniques.

 SR TOOL IVa04 – SRs WATER ALLOCATION
STRATEGIES BASED ON WATER PRODUCTIVITY
