“…The curve h has a unique maximum reached at the effective rate QD ( fig.1), whose analytical expression is solution of the derived function, h'(Q)=0. For more precision and in order to deal with different flow regimes, the analytical solution of the dominant discharge has been established for probability distributions other than the log-normal distribution, such as the normal, exponential or log-Pearson III distributions (Goodwin 2004;West and Niezgoda 2006;Quader et al, 2008;Higgins et al 2015).…”

around 9700 words against 10700 in the previous version). 3. The section title 'study area' was changed to 'study area and data collection'. Its text was rewritten from former sections 2 and 3.3 (in reply to referee #1's suggestion). A figure representing the watershed position was included. 5 4. Section 3 was fully revised according to the new thread. Subsection 3.3 was separated into three subparts, two of which moved to the introduction and to the revised section 2. Other subsections of section 3 are now based on the mean approach, the analytical approach, the half-load discharge and the return periods.5. The recurrence interval of a certain discharge like the effective discharge is traditionally calculated in 10 hydrology. However, this return period is only based on hydrologic distributions (from the distributions of mean and maximum discharge). We propose in this paper something more original, calculating a recurrence interval of the effective discharge compared to the distribution of annual half-load discharge, which was obtained from both water and sediment data time series, and investigate its additional information. The text was clarified accordingly. 15 6. Figure 3 was redrawn in semi-log scale.7. The comparison of the two calculations makes it possible to add information on the limits of the analytical method (based on a probability density function for the flow frequency). It did not provide good results in semi-arid environments because the sediment rating curve introduces errors (designed as 'of the first type' in the paper) and because pronounced asymmetric probability distributions failed to 20 reproduce good frequencies of high discharge (errors 'of second type'). Consequently, this comparison shows that the mean method by decomposition of histogram classes is the most suitable in a semiarid environment. This had never been tested in the literature. It's an original result. This was emphasized in subsection 5.4. 8. To be consistent all along the paper with the subsection "Elementary contributions and budgets", QY50 25 (i.e. the water discharge that delimits 50% of the cumulative sediment yield) was preferred to QY1/2 in the revised version of the paper. 4 Replies by the authorsThe paper is interesting and well within the scope of the journal, nevertheless it needs to be reinforced with reference to several points, mainly regarding paper clarity and organization.Reply: Thanks for the general comment and all your suggestions to makes the paper better organized and 5 clearer.The title should more informative and let the reader know that it deals with sediment transport and hydrological implications. Reply:We propose a new title: "Mean and analytical methods to characterize the efficiency of floods to move sediments in a small semi-arid basin". The mean method refers to the use of histograms where each 10 class of discharge is represented by its mean value, and the analytical method in which the dominant discharge is defined as the solution of h'(Q)=0 where h(Q)= f(Q).g(Q), f(Q) being a probability ...

Water flow and sedimentation processes have been significantly erratic at the Chókwè Irrigation Scheme (CIS) and have affected its hydraulic performance. Given its expansion there is need to understand these processes taking place on-site and along the channels of the scheme. CIS being the biggest project of its kind in Mozambique requires proper management of water flow and sedimentation processes. Therefore, the effect of water flow, sediment transport and deposition parameters on the performance of the CIS is needed. In order to determine the effect of spatial and temporal water flow and sediment distribution trends along the irrigation canals, there is need to establish a correlation between these parameters. Determining the influence of water flow velocity on sediment settling rate at different depths along the canal reaches is important in managing the CIS. In addition, a developed decision-support tool to predict sediment deposition is required. For this reason, it is therefore crucial to carry out a timely assessment of water flow and sedimentation processes in CIS in a review concept. From the current review, some gaps that exist for more focused research on Chókwè Irrigation Scheme have been identified. In this regard therefore, there is need to develop an effective support tool for managing water flow and sediment deposition along the canal reaches with a view to increasing crop production in CIS.

), and high values in shear stress (1.1-5.8 Pa) were obtained. It can be said therefore that in the River Magdalena predominates sediment transport in suspension. The values of bottom sediment transport calculated with the three formulations represent lower rates to 5% of total sediment transport. The formulation of Meyer-Peter & Müller (1948) underestimate the transport of bottom sediment due to the conditions under which it was originally calibrated, while Nielsen (1992) and Ribberink (1998) formulations can generate better estimates, because they were originally calibrated with fine sediment, similar to the sediment type reported in the study area.
