SSHCZO -- Streamflow / Discharge -- Discharge Reanalysis -- Shale Hills -- (2008-2015)

OVERVIEW

Description/Abstract

Flux-PIHM (Shi and Davis, 2013) was applied in August 2015 to reanalysis discharge in Shale Hills catchment. Flux-PIHM is a fully coupled land surface hydrologic model, which can be used to reproduce discharge, groundwater level, soil water content in different soil layers, snow depth, evapotranspiration, etc. This file present estimation of discharge and related hydrologic processes from Jan 2008 to Aug 2015 based on national databases and local measurement, in order to provide a continuous discharge estimation and to be a supplement of data in the case of data missing from field measurements.

Discharge units in reanalysis are often compared with precipitation and evapotranspiration, so it was expressed in m/day. It can be transformed to m^3/s by multiplying total area of sh (84710m^2) and being divided by 86400 (s/day):

Q = q(m/day)84710/86400 (m^3/s) = q(m/day)84710 (m^3/day), where q is the value in reanalysis results.
