This study opens interesting perspectives for the evaluation of distributed hydrological models using hydrological signatures. They however fail to provide quantitative information about catchment storage. The soil water content and a network of water level sensors provide interesting information about soil moisture and river flow dynamics. 2.1.3 Further crackdown following the uprisings in Tunisia and Egypt. There is strong indication of a deficiency in the characterization of catchment storage and upstream flowpath description. Results show that the non-calibrated model is quite effective at capturing water flow and soil water-storage dynamics, but it fails to reproduce observed runoff volume during events. Event timescales do also focus on the correlation between hydrological response and either rainfall event or antecedent soil moisture variables. The water level sensors network is used on two timescales: on a seasonal timescale, sensors network is used to assess the model’s ability to simulate intermittency whereas on event timescales, sensors network is used in determining the model’s ability to reproduce observed reaction as well as response times. Soil moisture sensors are used to assess the ability of the model to simulate seasonal water storage dynamics based on a normalized index. It includes standard water balance assessment as well as comparison of observed and simulated outlet discharge, whether on annual or event timescales. A stepwise approach is used for model evaluation. Thus, model parameters are specified either using in situ information or results from previous studies. ![]() The distributed water level and soil moisture network of sensors were useful in the model evaluation process. Model parameters are specified according to field data and a previous study performed in a neighbouring catchment (Jankowfsky et al., 2014), without calibration. The proposed methodology is illustrated using the PUMMA model in the Mercier sub-catchment (6.6 km 2). It proposes a general methodology for a diagnostic evaluation of a complex distributed hydrological model, based on discharge data at the outlet and additional distributed information such as water level and surface soil moisture data. Objectifs initiaux de l’action Irstea-HHLY Objectif 1: Etude des similitudes, diffrences et complmentarits des trois approches (IRIP, WaterSed, Exzeco) des inondations par ruissellement intense. In this review, we elaborate on reported methods and discuss recent advances and shortcomings in this area of tracking bacterial effector translocation.This paper emphasizes the importance of integrating outlet discharge and observed internal variables in the evaluation of distributed hydrological models outputs. Cartographies du risque li aux inondations par Ruissellement Intense (IRIP) : test mthode pour valuation nationale et contribution EPRI 2017. Recently, the existing toolset has been expanded by newly developed state-of-the art methods to monitor bacterial effector translocation and dynamics. Various approaches have been developed to understand timing and order of effector translocation, quantities of translocated effectors and their subcellular localization upon translocation into host cells. A comprehensive understanding of effector translocation in a spatio-temporal manner is of critical importance to gain insights into an effector’s mode of action. These effectors are translocated into host cells by means of dedicated secretion systems such as the type 3 secretion system (T3SS). Bacteria-host interactions are characterized by the delivery of bacterial virulence factors, i.e., effectors, into host cells where they counteract host immunity and exploit host responses allowing bacterial survival and spreading.
