• Add weather file (/Training/NamSVMod/rain_Phen.txd)

• Edit weather data interpolation change 0.002-> 0

• Change initial state (/Training/NamSVMod/ns_training_init.vms)

• Change pet calculation method to pan evaporation

• Add timeseries point (Nam Oon Dam)

• Add measurement file to the new timeseries point (/Training/NamSVMod/hq_NamOonDam.vms)

• Choose timeseries output variables

• Check computational parameters

• Run model

• Timeseries results, view qriver and precipitation results on Ban Tha Kok Daeng

• Flow comparison results, Ban Tha Kok Daeng• Tools in Results window• saving: as picture and as values• One timeseries: grouping statistics (average),

histogram • Two timeseries: R2 of common points, x-y plot• Selected timeseries: statistics, correlations• Editing pictures, change from line to dot, add header• bring together two timeseries• Results/Timeseries, results as table• Save project

Exercise 1

Compare the results from two different years at Ban Tha Kok Daeng (67,108) and Ts2 (138,80) + compare the measured and simulated flow at Ban Tha Kok Daeng– Use years 1992 and 1993– Compare the following parameters:

• qriver• prec

– Copy the result to word

Exercise 2

Simulate the difference in flow if the precipitation increases 10% and evaporation increases 5%– Use year 1992– Compare the following parameters:

• qriver• prec• etr

– Copy the result to word

Task 1 – sensitive analysis test• Objective: to understand the impact of different

parameters on the river flow• Task: do sensitive analysis for following parameters:

– Rainmult– Petcorr– Dz0– Mnover

use the ns_training.vmp as a basis. First calculate the model as it is for year 1992. Then increase the first parameter by 10% and compare to the base-result (average discharge at Ban Tha Kok Daeng). Then decrease the parameter by 10% based on the initial value and compare. Return the value for its original value. Repeat this to selected parameters

• Result: analysis of the sensitive of four parameters and their impact on the Q

Task 2 – deforestration

• Objective: to understand the impact of landuses on the model results

• Task: analyse how much the landuse change impacts on the model results. Use years 1990-1993. First run the model as it is and save the results at two stations: – Ban Tha Kok Daeng (67,108) – Ts2 (138,80)

then change all the landuse parameters from agriculture and irrigated agriculture to evergreen forest parameters (copy the parameters from the evergreen forest to agriculture and irrigated agriculture)

• Result: calculate the change in average flow at selected two stations and plot the graph where those two model run are compared

Task 3 – climate change

• Objective: to understand the impact of changes of precipitation and evaporation on the model results

• Task: analyse how much the climate change impact on the model results. Use years 1990-1993. First run the model as it is and save the results at two stations: – Ban Tha Kok Daeng (67,108) – Ts2 (138,80)

and save the results. Then increase the precipation 15 % and evaporation 7 % (change the rainmult and petcorr parameters in Landuse parameters... Menu). Compare the results

• Result: calculate the change in average flow at selected two stations and plot the graph where those two model run are compared

Returning the tasks

• Put all the results to one Word-document and send to Matti: matti.kummu@iki.fi by mid-June

• Any questions, write to Matti• From www.eia.fi/wup-fin you can

download the manuals • Next training planned for June, then the

objective is 3D model including sediment and erosion modelling
