HEC-RAS simulated historical and future streamflow dynamics in the lower Nemunas River Delta system

These data set contains HEC-RAS simulated streamflow across Lower Nemunas River Delta system. In the folder Streamflow across all river stations, there is a list of climate models: HadGEM, ICHEC, MPI, and IPSL folders. For each model, there are historical and projected folder. Historical for a period of (1975-2005), and projected for the near future (2020–2050) and far future scenarios (2069-2099) under both RCP4.5 and RCP8.5. The first row contains the date, the second column contains the river name and river station ID from upstream to downstream. For example, for Sesupe-113000: Sesupe is the name of a River, and 113390 is the river station. The second row represented streamflow in (m3/s). So, at the Sesupe River, river station (113390), at the date 01/01/1975 streamflow stream flow simulated was 4.16 m3/s. Table 1 shows an example of the CSV file for a historical period of (1975-2005). Table 1. Streamflow (m3/s) along the river stations Date Sesupe-113390 Sesupe-113000 Sesupe-112500 Sesupe-112000 Sesupe-111500 01/01/1975 4.16 4.17 4.17 4.17 4.18 01/02/1975 3.91 3.91 3.91 3.92 3.92 01/03/1975 3.65 3.66 3.66 3.67 3.67 01/04/1975 3.42 3.43 3.43 3.44 3.44 01/05/1975 3.19 3.2 3.2 3.21 3.21 01/06/1975 2.98 2.98 2.98 2.99 2.99 In the folder Streamflow at selected stations data set, there is a list of five gauging stations. For each gauging station, streamflow in (m3/s) for the historical (1975-2005), near future scenario (2020-2050), and far future (2069-2099) period were presented (please see Figure 1. Lower Nemunas River system and station locations). For each, the first column represented the recoded date (daily data), the second row represented the climate model and scenarios, for example, ICHEC RCP4.5 (2020-2050), HadGEM RCP4.5, and so on, streamflow data.
