Abstract:

This dataset has been collected thanks to the long-term partnership with Department of Agricultural Land Management (DALaM), Lao PDR, which granted the permission for field access, and to the financial, scientific, technical, and/or logistical support of the Multiscale TROPIcal CatchmentS (SNO M-TROPICS; <a href="https://mtropics.obs-mip.fr/">https://mtropics.obs-mip.fr/</a>) critical zone observatory (previously MSEC).<br><br> This .csv dataset includes Escherichia coli concentrations (MPN 100 mL-1) with upper and lower limits of the confidence interval, and physico-chemical measurements in stream water. Physico-chemical measurements include temperature (°C), electrical conductance (µS cm-1) at 25 °C, dissolved oxygen concentration (mg L-1) and saturation (%), pH (-), oxidation-reduction potential (mV), turbidity (NTU), suspended sediment concentration (g L-1). All variables were measured in the Mekong River in Luang Prabang (MK_17) and in five tributary catchments of the Mekong (Nam Khan: stations NK20 and NK26; Houay Khan: A6; Nam Ou: Nou_1; Nam Seuang: Nse_1), in northern Lao PDR. The monitoring includes measurements during low flow and high flow periods from May 2011 to May 2021.<br><br> The authors acknowledge the financial support of the Institut de Recherche pour le Développement (IRD), the GIS-Climat (Pastek program, <a href="http://www.gisclimat.fr/en/project/pastek.html">http://www.gisclimat.fr/en/project/pastek.html</a>), the French National Research Agency (TecItEasy project ANR-13-AGRO-0007; <a href="https://anr.fr/en/">https://anr.fr/en/</a>), the International Joint Laboratory on the impact of rapid Land use-change on Soil Ecosystem Services (LMI LUSES; ECOFILTER project; <a href="https://luses.ird.fr/">https://luses.ird.fr/</a>), and the French national grant EC2CO-Biohefect/Ecodyn//Dril/MicrobiEn (NARIBACT project).
